Shimano has introduced its new EP810 Series E-Bike System, featuring the DU-EP810 drive unit with up to 100Nm of torque, 750W of peak output and a claimed weight of 2.3kg. The system integrates third-generation AUTO SHIFT, AUTO ASSIST and a new range of connected components.

At the heart of the system is True Auto, which combines AUTO SHIFT and AUTO ASSIST to coordinate gear selection and motor assistance. AUTO SHIFT Gen 3 uses cadence, pedal torque, speed and gradient data to select gears automatically. Riders can also adjust their preferred shifting cadence directly through the bike's controls. The function requires a compatible Di2 electronic drivetrain.

AUTO ASSIST is integrated into the new TRAIL+ mode and dynamically adjusts motor assistance according to rider input and terrain. Assistance increases on climbs, decreases on descents and is managed on flatter sections to help conserve battery power.

Additional features include Hill Hold and Lift & Shift. When Walk Assist is activated on an incline, Hill Hold helps keep the bike in position when the rider stops. Lift & Shift allows the system to select a lower gear through a specific control sequence, helping riders restart after stopping on steep terrain. Assist Remain maintains smoother assistance when pedalling input becomes uneven or briefly decreases, while Assist Carry Over provides a short period of assistance after pedalling stops. The duration of Assist Carry Over can be adjusted.

The DU-EP810 features a magnesium alloy cover with integrated cooling fins and supports cadences of up to 160rpm. The system's components include the 720Wh BT-EN827 integrated down-tube battery, the SC-EN700 top-tube cycle computer, the SC-EM810 handlebar cycle computer, a wireless control switch, and the EC-EN832 2A and EC-EN834 4A chargers.

The SHIMANO CONNECT App supports system customisation, component updates, ride tracking and system locking. Ride tracking is scheduled to become available through an app update in spring 2027. Shimano's published materials do not specify pricing or a complete market launch schedule.
